Macomb, IL – This year's liberal arts lecture at Western Illinois University will examine why the humanities matter in a science-dominated world. The speech will be given by English professor Karen Mann, who will use film clips to illustrate her points. She believes scientists and humanists see the world differently, but she says there are similarities between the groups. Her presentation will begin at 7:30 p.m. on Wednesday September 7 at the University Union Grand Ballroom. The annual presentation is now named the John Hallwas Liberal Arts Lecture. Hallwas taught English at Western for many years and is a highly regarded regional historian and author. He delivered the inaugural liberal arts lecture in 2003.
